EDS In-Line High Volume Baggage Screening Project Washington Dulles International Airport

RESPONSES TO CONTRACTOR QUESTIONS #2 Date: August 10, 2011

1. From the RFP Section IX-4, "b. All offerors ... shall submit a Contract Participation Form (Exhibit D) with their offers. Exhibit D is to list all LDBE firms that are participating in the contract, ... the scope of their work ... and the agreed price for such work." In the LDBE outreach meeting, it was mentioned that the authority is requesting this requirement in order to prevent LDBEs from being "shopped." Given that the LDBE subcontractors are expected to be 20% of the job and the BHS vendor is expected to be 50-60% of the job, would it also be in the authority's best interest to have this same requirement extended to the BHS vendor in order to insure that the baggage number is not "shopped"?

RESPONSE: All first tier subcontractors are required to be listed on the Exhibit D.

2. From the RFP Section V-1 to V-2 "04 PRE-AWARD SURVEY. The Authority reserves the right to perform or to have performed, an on-site survey of the offeror's facilities or previous work products and to investigate its other capabilities. This survey will serve to verify the data and representations submitted, and to determine that the offeror has overall capability adequate to meet the contract requirements." Given that the BHS vendor is expected to be the majority scope of the job (50-60%) according to the authorities own account, would it also be in the authority's best interest to identify the BHS vendor at bid time so that the Authority can, at its own discretion, verify they have the "overall capability adequate to meet the contract requirements"?

RESPONSE: Yes

3. Given that the item number 1.23, Division 34 - Baggage Conveying Equipment contains a single unit price entry for input, is it the authorities intention that only one qualifying BHS vendor be offered as part of a contractors bid? From the RFP project summary, "This project will implement current-state-of-technology baggage handling and checked baggage inspection systems in the existing Main Terminal East and West baggage basements. It involves almost complete reconfiguration and replacement of the baggage conveyor systems and upgrade of conveyor controls ... all while maintaining current baggage handling and screening services capabilities for both the airlines and the Transportation Security Administration." Given the broad scope of this project involving almost complete reconfiguration and replacement of the baggage conveyor systems and upgrade of conveyor controls, the tight coordination required with the authority, airlines and vendors, and the need to maintain current baggage handling and screening services capabilities over the course of the over 1000 day schedule, is it the authorities intent and expectation that the baggage scope be awarded to one capable BHS vendor and that it would be too risky to be divided? If so, will the authority require that BHS vendors be named at bid time as well as provide citations of similar sized or larger projects completed in compliance with the TSA?

RESPONSE: There is no requirement that limits the contractor to one BHS vendor.

22. BHS qualification. In the Pre Proposal conference held June 7, 2011, it was mentioned that a prime contractor would need an Experienced BHS Vendor. In the References section of the General Requirements specifications, 01 42 00, page 3, WHEN USED with an entity, Experienced means having successfully completed a minimum of three previous projects similar in size and scope to this Project; being familiar with special requirements indicated; and having complied with requirements of authorities having jurisdiction. To help insure suitability of bids and to comply with your instructions, is it the authority’s intent that the proposing prime contractor provide evidence on bid day which fulfills this definition of an Experienced BHS Vendor by providing citations for at least three projects which are of similar size and scope for the chosen BHS vendor? If so to insure similar size, is it fair to say that the BHS vendors portion could be $50M to $75M given that as mentioned in the pre bid meeting, the budgeted value of this project is $100M to150M and the BHS portion could be 50% of the overall project? To insure similar scope, is it fair to say that only projects for a BHS vendor which meet these requirements, such as the Buy American clause and E verify for example, would qualify for experience?

RESPONSE: Acceptably qualified first tier BHS contractors / integrators for this project are listed in spec 347716, § 2.1.A.1. Prior experience with Buy American or E-Verify clauses is not required.

23. In some instances the Sequence drawings do not indicate fire/security door replacement where the baggage drawings indicate fire/security door replacement. Please confirm that for the curbside and ticket counter conveyors, all BHS fire/security doors along the K.4 column line are replaced.

RESPONSE: Confirmed, EBB doors can be referenced in section 34 77 16 – 1.2.D.3.d.1.)b.) and WBB in section 34 77 16 - 1.2.E.3.a.9.)a.)(2).

24. Transnorm requests the evaluation of the attached material for inclusion into the MWAA specifications as Approved as Equal for the following categories: 1. Powerturn 2. Spiral Powerturn

RESPONSE: Refer to Q&A # 14 of this document.

25. In the pre-bid meeting the Authority stated that CBP custom seals will be required for work on the West side. Obtaining a CBP custom seal on a traditional MWAA badge requires an additional security process and is very time consuming. Escorting of a badged employee by a badge custom sealed employee in CBP areas is not permitted by CBP or the Authority. Considering that no escorting is permitted in areas that require CBP custom seals, will the Authority consider giving the contractor of the East West Baggage Basement priority in obtaining custom seals due to the significantly drawn out badging process or will the contractor have to include the standard time it takes for this process without even being physically able to enter the work areas without this custom seal?

RESPONSE: The successful contractor will be provided no special priorities in obtaining CBP customs seals. Standard processing time should be assumed.

26. Specification Section 00-73-00 1.10 H states that when work is in CBP areas the Contractor is to secure necessary special security clearances to operate in CBP areas including obtaining a bond from CBP. The majority of the work on the West side is in CBP affected areas. Is the contractor responsible for the cost and time associated with obtaining these clearances?

Please confirm when restoring the conveyors that are not relocated to like-new condition - N of the K.4 Column line- the intent is to refurbish these conveyors in place, and the BHS subcontractor does not need to disassemble, transport, store, and reassemble the equipment.

RESPONSE: Confirmed, the intent is to refurbish in place.

35. The 34 77 16 BHS specifications do not state whether or not to re-use or supply new stainless steel shrouding for the public view conveyors noted to be refurbished. Please confirm the BHS subcontractor should re-use the stainless steel shrouding for the public view conveyors noted to be refurbished.

RESPONSE: Confirmed. BHS subcontractor shall plan to re-use existing stainless steel shrouding for refurbished conveyors and plan for new stainless steel shrouding for the new conveyors in the public area supplied as part of the Kiosk 4 reconfigurations, as specified in section 34 77 16 – 3.6.P.1.a.1.).

36. What is the advance notice requirement for utilities listed in Specification Section 011000-1.13.A? Due to the extensive nature of utility outages and its relationship with impacting baggage handling sequences and potential schedule implications will the Authority consider lessening the 3 weeks advance notice?

RESPONSE: Reference Specification 011000-7, 1.13 for all utility outages notifications. No, the advance notice will not be lessened at this time.

37. On past projects at the airport the MWAA code department has required multiple hydro tests for the fire suppression systems. At times the code department will require the contractor to break the testing in to sections determined by the official. How can the contractor consider the amount of time associated with hydro testing and pressure testing each branch-line with heads prior to tie-ins as it relates to schedule impacts? This work will have an effect on the Baggage Handling sequences. Can the code inspection requirement for this activity be clarified so the contractor can carry the correct amount of time and money associated with this?

RESPONSE: Contractor shall submit proposed testing plan and schedule for COTR approval, well in advance of scheduled work. Early planning by Contractor is the only realistic way to mitigate risks in this regard.

38. Specification Section 011000,1.13.B states that utility outage for fire protection detection are required to be scheduled 3 weeks in advance with 96 hours written notification to the COTR confirming the date, time and duration of the outage. Outage work is extremely dynamic and can change due to productivity. Is it the Authority intent for the Contractor to have to wait 3 weeks or 96 hours for an outage to get


Page 8 of 29

approved? Due to the fact that utility outage schedules will effect the Baggage Handling Sequences would the Authority consider shortening these durations to have less effect on the schedule of such a complex utility outage project?

RESPONSE: The intent is that the contractor shall schedule the outage and meet the schedule. The Authority cannot make that commitment at this time.

39. Specification Section 014000-1.2.A.3 states that the Contractor is not responsible for Special Inspection according to the Virginia Uniform Statewide Building Code (USBC) and that the Authority's agent shall provide these Special Inspection services. Are these inspections in addition to the testing which the Contractor owes in the specifications for quality control?

RESPONSE: Yes

40. Does the Special inspection relieve the Contractor from any testing requirements which are covered by these Special Inspection services?

RESPONSE: No.

41. Is it the intent of the Authority to have 48 hours notice provided for Special Inspections which can have significant impacts to close-ins and pours and schedule implications on the project?

RESPONSE: Yes

42. Please confirm that the following items are required to be inspected per USBC and MWAA Code: duct banks, site utilities, mechanical piping, plumbing piping, framing, electrical systems, fire protection systems, preparatory work prior to the placement of concrete, duct work, insulation and fire alarm.

RESPONSE: Yes

43. Per Specification Section 014000-1.15.F Code Inspection Request are required 48 hours in advance. Traditionally PMC inspectors are required to verify and agree that the segment of work is ready for inspection prior to forwarding the Code Inspection Request on to the MWAA Code Department. Once PMC has verified the work then the Contractor can call for the code inspection. This process takes several working days and has a significant amount of impact on the schedule. Will the Authority consider implementing a different MWAA Code Inspection process for the East West Bag Basement Project?

RESPONSE: No.

44. Workers, materials and equipment are required to enter the AOA via gates 313, 317, 141, or 118. Only gates 118 and 141 are designated as AOA escorting gates. At these gates all vehicles are searched, all vehicle deliveries must be coordinated in advance, escort vehicles are required. During this process a significant amount of productive time is lost. Will the Authority consider providing the Contractor of the East West Bag Basement special provisions to enter the AOA or should the contractor carry the lost time for traditional labor, equipment and materials entry to gates 313, 317, 141, and 118?

RESPONSE: No special provisions. Offer amount includes time, equipment, etc for the above items.


Page 9 of 29

45. The East and West Bag Basements are separated by a significant distance. Can the Contractor assume that materials, tools and equipment can be transported thorough public areas from East to West and vice versa or is the general contractor to provide escorting vehicles to move materials and equipment from East and West sides?

RESPONSE: No transit through public areas to get from East to West portions of the project. Pedestrian or vehicular traffic airside will be necessary.

46. Should the contractor carry time and cost for jurisdictional fire permits including storage of hazardous materials, hot work permits etc?

RESPONSE: Yes, the offer amount includes time, equipment, etc for the above items – the Authority is its own jurisdictional authority in these matters.

47. Drawing Sheet GN00.0003 shows that the only access for hauling from Construction Area E.E to be a very small area between the MU-2 building and the Advanced East new Tug tunnel. This area is going to be United Airlines access point for two way tug traffic for the South Bag Basement tug tunnel, 2 way tug traffic for the East Bag Basement Ground floor, two way tug traffic for the East Bag Basement, and one way tug traffic to MU-2 building. Drawing sheet GN03.0600 sheet 123 General Phasing Notes 2 states All perimeter construction barricades around all exterior work and adjacent to baggage tug traffic shall be performed between the hours of 11:00pm and 4:00am. The excavation and construction is adjacent to significant UAL tug traffic operations. Is it the Authority’s intent that the hauling and construction for the East Bag Basement extension be at night?

RESPONSE: It is not the intent to restrict the hauling and construction for the East Bag Basement extension to take place at between 11:00 pm - 4:00 am only. Reference General Phasing Notes on GN03.0600 and coordinate with COTR on construction vehicles and dump trucks accessing the site.

48. Specification Section 00-73-00 1.5 G states maintain a vacuum-sweeper and flusher truck at the site at all times to clean roadway and aircraft surfaces affected by construction traffic at the request of Airport Operations or the COTR. In the past the Authority has strictly enforced the requirement for sweeper trucks to be on site full time regardless of what type of construction is occurring. Is it the Authority intent for the contractor to have a sweeper truck and operator on site for the 37 month duration of the project?

RESPONSE: Yes

49. Division 347716 page 147 Letter D Number 1 b: Please list ControlTouch Systems as an approved subcontractor for the re-control of the Crisplant Sorter. We have successfully completed similar scopes of work at Newark and Houston.

60. From page 170 of the baggage specification, "3. A minimum of two drive units are required for all baggage claim applications due to redundancy requirements. As part of the reconfiguration / recontrol of claim devices CD13 and CD14, provide an additional drive for these claim devices and modify the referenced claim devices to accommodate the addition of the new drive." Who is the manufacturer of the existing CD13 and CD14 that require modification to provide additional drives?

RESPONSE: Existing claim devices which shall be renumbered as CD13 & CD14 were manufactured by G & T.

61. We are not in receipt of drawing SC05.0000. Please provide. Additionally drawing SC05.0002 is included in the documents but is not on the drawing index. Please confirm.

RESPONSE: There are no drawings missing. The Drawing Index on sheet GN01.0002 is at variance with the drawing numbers assigned for the Support of Excavation Elevations.Sheet name of 1st elevations (Sheet 327 of 1854) is SC05.0001, not SC05.0000 as shown in the Index.Sheet name of 2nd elevations (Sheet 328 of 1854) is SC05.0002, not SC05.0001 as shown in the Index.

62. Please clarify the location and costs for contractor parking.

RESPONSE: The land-side contractor staging area is in a large area set aside for this and other contract staging. This area is east of AOA Gate 313, on the south side of airport property, and is accessed via Route 50 and Stonecroft Blvd. It is approximately 3¾ miles from the project site. Drive time, not including processing time at Gate 313, is typically about 15 minutes. There are not costs for parking in these areas.

63. Reference 012100 Allowances 2a. Please clarify the intent of 1.6.B where it states the Contractors costs for receiving and handling at Project site, labor, installation, overhead and profit and similar costs related to products and materials ordered by Owner under allowance shall be included as part of the Contract Sum and not part of the allowance. This presents a conflict with the descriptions - can we presume the allowance includes the installation?

69. In section 01 21 00 para 1.6 Lump Sum allowances it states; Contractors costs for receiving and handling at Project Site, labor, installation, overhead and profit and similar costs related to products and materials ordered by Owner under allowance shall be included as part of the Contract Sum and not part of the allowance. We understand the OH and profit as this simply puts the allowances above the line within our overall bid. For all other items this is simply not possible to discern or estimate the costs and it seems to be in contradiction with the language within the allowances. a. For instance Haul road Repair allowance of $565,000 - how does this not contain costs for labor and installation? b. Is it intended that the subcontractors OH and profit be outside these allowances as well. That would not be possible as some of these allowances will entail new contracts be issued. c. What is meant by and similar costs related to products and materials ordered by Owner? Please review and modify the language. Without this modification or specific quantification of materials and components it is not possible to estimate the work associated with each allowance for material handling or installation.

RESPONSE: See Addendum #1 in forthcoming Amendment. Specification will be revised.

90. BHS Spec. page 548, System Endurance Test. Please confirm that the WBB and EBB will have one test performed at the completion of each system.

RESPONSE: Confirmed that each baggage basement shall have one System Endurance Test as specified in section 34 77 16 – 4.2.A.2.f.11.).

91. Specification section 00-73-00 1.16 E states: provide the services of at least one full time on site Contractor Safety Engineer per construction work shift for each baggage basement with no other duties assigned who shall work under the direction of the Contractor Safety Manager. Is it the Authorities intent for the Contractor to carry 5 full time safety professional employees for 37 months if the project requires 2 shifts?

RESPONSE: Safety Manager position is full-time during full duration of all work performance. Contractor’s detailed Work Plan will dictate Safety Engineer staffing required to cover all construction work shifts in each basement.

92. Specification section 014000 1.9 requires that the General Contractor is to provide the following separate individual positions 1. Project Manager, 2. Project Superintendent, 3. Quality Control Manager, 4. Alternate QCM, 5. QC Specialists for Coordination, 6. Registered Fire Protection Engineer, 7. Mechanical Quality Inspectors, 8. Electrical Quality Inspectors, 9.

Of these 18 specified positions 9 are required to Registered Professional Engineers. The cost associated with these staff positions is significant. Is it the Authority’s intent for the General Contractor to have 18 professionals on staff for 37 months in which 9 are registered professional engineers?


Page 17 of 29

RESPONSE: Contractor’s detailed Work Plan will obviously dictate staffing required to cover all construction work shifts in each basement by the respective quality inspectors referenced above.

93. Is the contractor required to carry the cost for developing a full set of CADD record as-built drawings for the project?

RESPONSE: Yes

94. Specification section 011000-1.13C requires that outages related Central CHW be performed between October and April and Central HTHW be performed between April and October. Due to the extensive utility outage requirements of this project this could have significant schedule implications. Certain Baggage Handling sequences may be effected by the these utilities and if the Outages need to occur in a certain season and they are in a different season the wait time to perform these BHS sequences could be up to 7 months. This will have significant schedule implications. Will the Authority consider waiving these requirements?

RESPONSE: No. Significant outages should be required only for cut-in of new isolation valves.These cut-ins are expected to be accomplished in their respective off-seasons and need not be concurrent with other downstream HTHW/CHW piping work.

95. The RFP states that the Authority will award a Contract resulting from this solicitation to the lowest responsive, responsible offeror meeting the Minimum Responsibility Requirements specified in Section X, Attachment 06. Section X, Attachment 06 states the Contractor shall have successfully performed three or more multi-trade critical-industrial or airport terminal/concourse projects within the last 7 years, each with a value of approximately 50 million or more, and each of which included self-performance of, or supervisory and inter-trade coordination responsibility for, all of the following: automated baggage handling systems; electrical power and lighting; cast-in-place building structural concrete; deep excavation and excavation support systems; HVAC; and plumbing and fire protection. Please confirm the Authority will not award this project to a Contractor that does not meet all of the requirements listed above.


96. The MWAA Code department is required to inspect a significant amount of work elements in order for follow on work to occur. Code Inspections require at least a 48 hour advance notice and PMC is required to verify if the Contractor is even ready to call for a code inspection. This means that the work needs to be completed and inspected by PMC prior to being able to call in for code inspections. Calling for code inspections on anticipated completion of work items has not been accepted. On past projects the Authorities code department can show up for scheduled 7am code inspection at 2pm causing the contractor to lose an entire day before being able to perform follow on work. This may have schedule implications on a project of this nature. Much of the work on this project is going to be performed between the hours of 11pm and 4am. On this project close ins and inspection may need to occur at night in order for follow on work to proceed. In order to support the construction schedule for this project will the Authority consider allowing code inspection to occur between the hours of 11pm and 4am?

RESPONSE: This can generally be accommodated with 3 business days advance notice to the COTR.


Page 18 of 29

97. The RFP Price Schedule under Contract Milestones and Liquidated Damages contains the following language which is problematic for the bidders. In addition, should any individual BHS Sequence Step not-to-exceed outage duration in the contract documents be exceeded by Contractor, Contractor will be back-charged for additional manual baggage handling costs incurred by the Authority and-or the airlines, and-or other additional airlines operating costs. In discussion with the subcontracting community, there have been questions as to how to price this indeterminate risk. In general, we as the contracting community, do not have a good knowledge of the direct costs for the airline or airport operations and have a general lack of understanding of airline and airport indirect costs. It is likely that an airline or the airport could attempt to assess substantial consequential costs in the event of an unplanned extended outage. We respectfully ask that MWAA work with the airlines to determine a fair and reasonable liquidated damage for extended outage duration such as a cost per hour or cost per day and issue this amount as an addenda in lieu of the general statement above. In this manner we can properly understand our risks and price them in a competitive manner and in addition assure our sureties that we are not facing a situation of unknown, uncapped and potentially excessive damages

RESPONSE: Refer to revised language in Solicitation Section III – Price Schedule, issued with Amendment 4.

98. The [liquidation damages] phrase, (In addition, should any individual BHS Sequence or Step not-to-exceed outage duration in the contract documents be exceeded by Contractor, Contractor will be back-charged for additional manual baggage handling costs incurred by the Authority and or the airlines, and or other additional airlines operating costs.) The other additional airlines operating costs creates an undefined consequential damage that is not acceptable to the surety providing payment and performance bonds for the contract. We request that the authority remove this clause from the agreement and include a mutual waiver of consequential damages clause.


99. The Authority’s standing policy regarding delay damages, as noted in its contract provision #43, is to specify liquidated damages as the sole and exclusive remedy for delay because of the expense and difficulties involved in proving an actual loss for failure to complete on time. In Section III, Price Proposal, Contract Milestones and Liquidated Damages the Authority has negated this policy by allowing for back charges for additional manual baggage handling costs incurred by the Authority and or the airlines and/or other additional airlines operating costs for failure to meet a BHS Sequence Step not to exceed outage date. These additional damages for failure to these milestones shift an incalculable monetary risk to the contractor which cannot be adequately priced and may be based on activities outside the control of the contractor. Will the Authority agree to remove the provision for these additional damages? Will the Authority agree to state the amount of said damages or agree to cap the overall amount of these damages?


100. Please clarify the damages listed on the bid form. It appears as if there are Liquidated damages and actual damages. Is the intent to have actual damages for the BHS Sequences and Outage durations only and Liquidated damages for the substantial Completion only or is it the intent to have liquidated and


Page 19 of 29

actual damages for all milestones. Liquidated damages are typically for exclusive remedy for delay and both liquidated and actual damages would be not assessed.


101. In reviewing the specification requirements for submittals and close out documentation, it appears that the shear volume of paperwork is significant and largely unnecessary for all parties, not to mention costly to MWAA. Utilizing technology that has largely been embraced in the industry to promote "Green Projects" would the Airports Authority, PMC and SOM waive the requirements for paper submittals and close out documents-record documents and allow for a more "green" project by the use of electronic submittals where appropriate and close out documentation-record documents?

RESPONSE: No.

102. Can the project specifications regarding submittals, section 01 33 00, require one electronic submission and a minimum of two paper copies be submitted for submittal product data etc. will the electronic submission be returned containing the denotations conducted by the designer-owner-consultants?

RESPONSE: No.

103. May specification sections that require multiple copies of paper project documents , submittals, product date, photos etc, be modified to allow for electronic submissions? The implementation of a paperless project will result in a less expensive, more controlled process, project lifetime access to project related documentation, security, utilization of electronic drawings in the field resulting in a safer & more productive work environment resulting in higher quality control and communication among team members.

RESPONSE: No.

104. From the Price Schedule provided, it explains the following: East Basement BHS Sequence E13, E14, and E15 needs to be complete from NTP within 902 calendar days from NTP, and - West Basement BHS Sequence W13 needs to be complete from NTP within 967 calendar days from NTP, and - Achieve Substantial Completion within 1,100 calendar days from NTP Following Substantial Completion, how much time is allowed to reach Final Completion? Please clarify.

RESPONSE: Time allowed to reach Final Completion will be stated in documentation provided by the COTR issued with the Substantial Completion certificate and final punchlist.

105. Please confirm that the BHS Contractors price is to include matching the SBB existing components listed in Exhibit A. For example, Allen Bradley PF70 VFDs and Allen Bradley 5000 Series Photoeyes

RESPONSE: Yes, refer to specification section 34 77 16 – 2.1.F.2.

106. Please refer to Dwg BG10.1001 sheet number 1588. The last table on the page shows an optional MCP WED2C for optional conveyors WED2C. Are we to quote this option? If so, can you please supply a drawing that shows these conveyors?


Page 20 of 29

RESPONSE: Optional conveyors and associated MCP are not required to be priced; refer to specification section 34 77 16 – 1.2.B.10.

107. Please refer to Dwg BG10.2001 sheet number 1596. The last table on this drawing shows optional MCP ID's for EED2 (Opt) (A) and EED2 (Opt) (B) and subsystem named conveyors EED2-02/18 and EED2-18/25 & ECB2-01/05. This is not clear as the layouts for the base bid have conveyors EED2-01 through EED2-19 and ECB2-01 through ECB2-44. Please clarify what conveyors/MCPs are to be quoted as part of this option?

RESPONSE: Optional conveyors and associated MCP are not required to be priced; refer to specification section 34 77 16 – 1.2.B.10.

108. Please confirm that all manual baggage handling; porters, carting, tagging etc is not to be included under this contract and that the work will be conducted by others.


109. Will X-raying and or Ferro Scanning of both SOG and elevated slabs be required for demolition, MEP & Baggage hangers? If so could you please confirm thickness of slabs so that it may be determine if conventional methods are applicable or are methods such a Cobalt required? Can the use of 2.5 in anchors, pins etc be established as a max tolerance for embedded items without the use of detection methods

RESPONSE:a) Yes, Specification section 01 73 29 covers methods of locating reinforcing and other embedded items. b) Methods as detailed in 01 73 29 are applicable.c) No.

110. Please provide Airport and Airline blackout periods during which work may not be performed for the duration of the project for the west side operations, customs area operations and the east side operations. This information is critical to project planning, scheduling as well as the assessment of the baggage line outages contained in the RFP.

RESPONSE: Contractor is required to conform to project phasing requirements and work hours restrictions as indicated in specifications and drawings. BHS sequencing reflects out-of-service duration and limitations. Contractor is required to coordinate with COTR on outage. For work hours restrictions, refer to General Phasing Notes on GN03.0100 and GN03.0600.

Periods in which the contractor will not be allowed to have conveyor or other BHS subsystem outages include: Easter Weekend: Thursday Noon before until Monday Noon after (96 hours). Thanksgiving:Thursday Noon before until Monday Noon after (264 hours). Christmas/New Year’s: Generally from 3 full business days prior to Christmas until 1 full business day after New Year’s (total number of hours varies year-year based on calendar).

111. Specification section 34 77 16 1.1C1 states that Information regarding existing conveyor equipment designated for modification or to remain, such as but not limited to mechanical, electrical as-built documents-information, O&M Manuals, software, computer-PLC architecture and layout drawings-


Page 21 of 29

documents, source codes and other relative documentation relating to the existing BHS, shall be obtained from the Authority, their Maintenance Group or United Airline (in case of EBB), through the COTR. Could you please inform the bidders as to when this information will be provided relative to the NTP issuance to the successful bidder?

RESPONSE: Available documentation will be provided to contractor not later than 45 calendar days after contract NTP.

112. As counted from NTP, when is the latest that all code including the PLC code and the Crisplant code can be expected to be delivered to the contractor/ BHS vendor?

RESPONSE: Available documentation will be provided to contractor not later than 45 calendar days after contract NTP.

113. Please refer to Sec 015000, 1.8.B. Where is the parking lot located and what is monthly cost of permit?

RESPONSE: The land-side contractor staging area is in a large area set aside for this and other contract staging. This area is east of AOA Gate 313, on the south side of airport property, and is accessed via Route 50 and Stonecroft Blvd. It is approximately 3¾ miles from the project site. Drive time, not including processing time at Gate 313, is typically about 15 minutes. There is no cost for parking in these areas.

114. Please refer to Sec 347716, 3.14.A & C.2. Please give direction as to the extent and limits of refurbishment?

RESPONSE: Refer to requirements in above referenced specification sections.

115. Please refer to BHS specification 1.2-B.20, page 8. "The Main Terminal ceiling structure within the EBB and WBB includes an existing unistrut system (embedded in the ceiling structure). Take on the responsibility to use, as much as possible, the existing and new unistrut systems, wherever it accommodates the new and reconfigured BHS to avoid drilling into the ceiling concrete, wherever possible." Will any drilling in the ceiling be allowed with prior x-raying?

RESPONSE: Specification section 01 73 29 covers methods of locating reinforcing and other embedded items, and is required prior to drilling.

116. Note #10, under Reinforcing Steel, on the Structural General Notes-1 drawing ST00.0001 states, All reinforcing steel shall be epoxy coated IAW ASTM A 775. Please clarify that this means all of the reinforcing steel in the project is to be epoxy coated.

117. With regard to Project Phasing WBB(GN03.0100)and EBB (GN03.0600). The cumulative total of the sequence durations shown in the tables on GN03.0101 and GN03.0606 are significantly less than the contractual dates contained in Section III - Price Schedule. Please delete the sequence durations and confirm that the BHS Contractor can develop a schedule to execute the project in accordance with the outage durations and dates contained in the Price Schedule.

RESPONSE: No.

118. With regard to Project Phasing EBB SEQ E12 - Step 3 (GN03.0606) references an "extended overnight connection" for OS4 and OS4A. GN03.0756 shows two Step 3 detail plans that contain OS4A conveyors. Please clarify and confirm that the OS4-02 thru 08 and ECB1-26 are not required to be installed overnight.

RESPONSE: Confirmed; refer to drawing GN03.0608 which indicates the intent for the installation activities associated to Sequence E12, Step 3.

119. Regarding Servers. Section 2.14-E.2.e seems to indicate by its grammatical construction that the SAC and MIS functions may be combined on a single server. Section 1.2-Q.3 indicates that MIS reports shall be able to be generated in real time, assumed to mean during operations. Request: Please identify how this functionality will be assured without impacting live server operations if the SAC and MIS applications are permitted to be on the same server.

RESPONSE: As stated in section 34 77 16 – 2.14.A, it is the Contractor’s responsibility to meet the overall functional requirements for the definitive architecture, design and engineering of the system and comply with the specified performance requirements.

120. Regarding VFDs: Section 2.10.D.2.b discusses both VFD rated cables and #10 gauge wiring. This section seems to indicate that #10 THHN gauge wiring may be used if Rockwell Powerflex 70 guidelines permit such use. Section 2.10.4.w.7 indicates that under the base scope of work, all VFDs are to be MCP mounted (an alternate may be submitted for field mounting). Based on current guidelines for VFD output wiring, if the wire length distance between VFD and motor connection exceeds 30 ft, manufacturer recommends utilization of VFD rated cables comprised of XLPE type insulated conductors. Request: Please clarify what is expected in design and construction - use of VFD rated cables or THHN conductors in conduit, as this will have a significant cost impact.

RESPONSE: As noted in the above referenced specification sections, the BHS Contractor shall comply with the specified requirements and the VFD OEM requirements (as applicable) in their design and construction.

121. Reference 34 77 16 1.2.D.4.b page 26. Is it intended that the new manual encode consoles in the EBB and WBB be identical to the interim manual encode consoles?

RESPONSE: Not confirmed; refer to specified interface and reporting requirements in section 34 77 16 – 2.14.B.1.e.2.) with respect to the ATR/PLC interface and section 34 77 16 – 2.14.C.9.e for interface to UAL’s Baggage Reconciliation System.

123. During the LDBE event it was mentioned that a non reimbursable bond cost is to be included by the contractors for access to the International terminal areas for additional security badging and clearances. Please provide the cost and process to obtain this special access or provide the requirements of the bond that will be required.

RESPONSE: A customs bond and seals for employees are required for access to international areas. The bond is nonreimbursable and costs $25,000 to register 1 -15 employees with a seal. See the Customs Seal and Application document for additional information.
